Fibrinogen, the precursor of fibrin in the coagulation cascade, is also a protein of the acute phase of inflammation, and it is the major determinant of plasma viscosity, all risk factors involved in the genesis of atherosclerotic vascular disease. The aim of this study was to evaluate the association between the fibrinogen plasma levels and blood pressure measured by ambulatory monitoring in 24 hours.

Materials and methods

In our study we examined 360 patients with ischemic heart disease and/or hypertensive heart disease. All patients underwent cardiovascular examination, laboratory tests, ambulatory blood pressure monitoring and 24-hour Holter-ECG. Our population was then divided into tertiles according to the plasma fibrinogen levels (1st tertile 272 + 26 mg/dl; 2nd tertile 338 + 19 mg/dl; 3rd tertile 468 + 86 mg/dl).


Our data showed no statistically significant differences between the values of systolic and diastolic blood pressure (SPBC, DBPC) detected by mercury sphygmomanometer, in the 3rd tertile of plasma fibrinogen than 2nd and 1st tertile. On the other hand, mean values of the systolic ambulatory blood pressure, of the 24 hours blood pressure (SBP 24h), of the day-time (SBPD) and night-time (SBPN) pressure were significantly higher in the 3rd tertile than 2nd or 1st tertile of fibrinogen. Moreover, we observed a statistically significant reduction of the mean values of diastolic pressure of 24 hours (DBP24h), of diurnal (DBPD) and nocturnal (DBPN) pressure, resulting in significant increase in values of pulse pressure (PP), in the 3rd tertile than 2nd or 1st tertile of fibrinogen. In conclusion, our data showed that in the elderly patients high plasma fibrinogen levels are significantly correlated with the values of systolic and diastolic ambulatory blood pressure monitoring and the mean values of heart-rate. Moreover, the analysis of individual tertiles showed a prevalence of atherosclerotic coronary disease significantly higher in the 3rd tertile of fibrinogen (76% vs. 55% and 35%, p = 0001) than 2nd and 1st tertile.


Our data confirm that high levels of fibrinogen are associated with atherosclerotic coronary disease and represent a risk factor for cardiovascular disease in elderly patients.
